just start off with the clio v6 for pro leauge 1/2 mile, then win the bmw 328i in the career mode then you will be off to a good start with level one, or as you have seen you will never get a hall of fame (5000 points) with any other car apart from the top car for that level, try bet and race for building your RP's as they are more important than money, as money comes in quicker than rps, you say you have a lambo use that, most cars dont need maxed out you will find they domanate a level without been fully upgraded as the case for the clio level one = 111052, but fully upgraded will go to lev3 a think and ford boss is best there, . hope this helps you out,
